hi

i followed the instructions, selenium server is running

$ java -jar selenium-server-standalone-3.141.59.jar

and chromedriver is in the PATH

when executing any test, it fails with status 500 when establishing a session

selenium output just says

12:45:18.160 INFO [ActiveSessionFactory.apply] - Capabilities are: {
  "browserName": "chrome"
}
12:45:18.161 INFO [ActiveSessionFactory.lambda$apply$11] - Matched factory org.openqa.selenium.grid.session.remote.ServicedSession$Factory (provider: org.openqa.selenium.chrome.ChromeDriverService)

any idea what i am doing wrong or how to debug?

I am also getting the same error.

I doubt localhost below routes works for selenium webdriver -
http://localhost:4444/wd/hub/session/
http://localhost:4444/wd/hub/session/<session_id>/url etc ..

in webdriver.rs
looks like below code is trying the session route while constructing url.
let url = construct_url(vec!["session/"]);

I am not sure how these "http://localhost:4444/wd/hub/session/<session_id>/url " works ?

let url = construct_url(vec![
"session/",
&(self.session_id.clone().unwrap() + "/"),
"url",
]);

weird..

just reopened the project in my IDE after 2 months without touching anything in between. Started selenium and ran the tests: success ✔️

Sorry @davnav I cannot reproduce it anymore..

@globalworming Which version of chromedriver are you using? I'm using the latest version (of chromedriver) and I'm seeing the same 500 error on all tests.

$ chromedriver --version
ChromeDriver 87.0.4280.88 (89e2380a3e36c3464b5dd1302349b1382549290d-refs/branch-heads/4280@{#1761})

[globalworming]

don't know which version i was running at that time :)

No worries. I figured out that I had to have the Chrome and chromedriver using the same versions. I'm now using both Chrome and chromedriver on 88.0.4324.96 and no longer getting the Error(Status(500), "http://localhost:4444/wd/hub/session/" errors.

I am though getting the error Error(Json (Error ("invalid type: null, expected a string", line: 3, column: 19)) (issues #35 and #34), but that may be outside the scope of this issue.
